I'd suggest adding extra anchor points, a couple of times, getting them back in a GIS and simplifying them there.

Alternatively, tinker with the pathfinder tools. There should be a way to break the polygons down to single boundaries. If you manage to do that, then you can easily simplify the single lines without fear of introducing gaps and afterwards build polygons from them again.

Just to let you all know, Avenza is deep into working on a new and much improved simplification function for a future MAPublisher release which will accomplish what you want.
Rest assured that the MAPublisher folks are, as always, on top of the issues that concern cartographers and map-makers in order to make their lives easier.

Thanks Nick for the lead - am trying to see how far I can go with this - may need to hunt down a joining script.

This is great news, Ted. May I suggest another function? This may be a long shot, but....now that painstaking manual cartographic work seems to be a thing of the past, it would be nice to automate the dropping of contour lines in steep slope areas. Ideally the function would take into account contour line weight at the scale of presentation, and automatically delete segments of selected contours based on a palette of options. The options could be based on, say, the rules that the Canadian Federal Government used for this kind of situation. (see http://maps.nrcan.gc...inIndexE250.htm ) Oh, and while we're at it -- maybe depression contours with ticks! Surfer does that, but it would be nice not to have to go through that loop if possible.

This is a reverse engineering question - I have run across a set of state polygons that have hyper Bezier curves from being simplified in Illustrator.But NO GAPS between polygons.

My hunch is these were not hand traced (its from a world political map), so how can you do this in Illy? Simplify polygons and keep boundaries snapped together?

I m intrigued!

Sample below:

If you don't mind losing your colours then try this:

- Select all Polygons (you probably have to make sure they are all ungrouped etc)- Pathfinder > Outline (breaks at joins and removes duplicate boundaries)- simplyfy as desired- Pathfinder > Divide (Creates new Polygons from these boundaries)- Now go back to setting your colours again...

Hope that helps.
